During the annual demand for the amount of the metal sealing
sanitary
ball valve, the electric power industry is about 200 million
yuan, about 600 million yuan in coal chemical industry, petroleum
chemical metallurgy industry is about 240 million yuan. Total
annual demand is about 1 billion 240 million yuan.

As a fluid transfer valve component, with the national economy,
especially the development of the national coal chemical industry
and equipment manufacturing industry, put forward new
requirements for sanitary
valves: high temperature, wear resistance, corrosion
resistance, erosion resistance, thermal cycle and zero leakage,
in the new economy, the development of metal sealing ball valve
will be rapid.
